Control Valve Actuators Basic Principles of Control

The purpose of a control valve actuator is to provide the motive force to operate a valve mechanism. Both sliding-stem and rotary control valves enjoy the same selection of actuators: pneumatic, hydraulic, electric motor, and hand (manual). Pneumatic actuators. Pneumatic actuators use air pressure pushing against either a flexible diaphragm or a piston to move a valve mechanism.

How It Works: Actuators Schlumberger

2015-1-8  At a basic level, an actuator is a control mechanism that is operated by an energy source. This energy—hydraulic pressure, pneumatic pressure, or electric current—moves the internal mechanical parts of the actuator. Actuators can be designed to fail open (in the case of actuator failure, the valve will stay open) or fail close (in the case
